Optimal Duration of Stretching of the Hamstring Muscle Group in Elderly: A Randomized Controlled Trial

Not Applicable
Conditions
Stretch
Registration Number
NCT04459832
Lead Sponsor
Cairo University
Brief Summary

identification of optimal duration for hamstring muscle stretch by using 3 different time of stretch 15,30,60 seconds .100 subjects will be participated in this study divided into 4 group one control and 3 experimental groups according to stretch time.

Detailed Description

Abstract:

OBJECTIVE: To explore the effect of variable stretching intervals on neural function and ROM.

DESIGN: Randomized controlled trial Participants: In this trial, 100 participants will participate in the study diagnosed with tight hamstring muscles (defined as the inability to extend the knee to less than 20° of knee flexion) were randomly assigned to the control group or one of the 3 intervention groups Interventions: The three experimental groups will stretched 5 times per week for 4 weeks for 15, 30, and 60 seconds, respectively the control group did not stretch Main Outcome Measures: The neurophysiological outcome measures included peak to peak somatosensory evoked potential for dermatomes L3,L4,L5, and S1. Secondary outcome measures included knee ROM. All outcome measures will be assessed immediately after the treatment session and 24 hours after the treatment session.

Recruitment & Eligibility

Status
UNKNOWN
Sex
All
Target Recruitment
105
Inclusion Criteria
  • Subjects had to demonstrate "tight" hamstring muscles, defined as inability to extend the knee to less than 20 degrees of knee flexion with the femur held at 90 degrees of hip flexion while the person was positioned supine. Subjects were also screened to rule out knee joint flexion contractures by checking knee extension ROM, while they were lying in a prone position
Exclusion Criteria
  • Using of medical aids, and suffering from any neurological or cognitive impairment, limiting cardio-respiratory conditions, or had undergone recent surgery (within the past 12 months). Having any hip or knee replacements or any history of pathology in the low back, hips, or knees for the 3 months prior to the study

Primary Outcome Measures
NameTimeMethod
Neurophysiological findings.Assessments of the change of DSSEPs from baseline to immediatly after session and at 24 hour after session

Neurophysiological findings included peak to peak somatosensory evoked potentials (DSSEPs) for L3,L4,L5,S1 dermatomes.

Secondary Outcome Measures
NameTimeMethod
ROMAssessments of the change of Knee ROM from baseline to immediatly after session and at 24 hour after session

Each subject was then measured for knee extension ROM on both lower extremities
